Abstract: Potato early blight caused by Alternaria solani and Alternaria alternata is a major disease of potatoes and other Solanaceae. By now, Alternaria species have established themselves as destructive pathogens. Due to considerable yield losses early blight is getting a serious problem in many German potato growing areas. Up to now, the management of this disease is achieved mainly through protective fungicide applications. By this, fungicides with different mode of actions have a considerable influence on the course of disease progress. For this, field trials were carried out in 2007 and 2008 and the efficacy of various active ingredients was determined. Marked differences were observed in the control of early blight disease due to the effectiveness of applied active ingredients. The application of potent fungicides, which are highly efficient, resulted in prolonged photosynthesis. As a result of this potato yield increased significantly. Our investigation show, that disease control can be better achieved with strobilurines like Azoxystrobin or Boscalid + Pyraclostrobin than with Mancozeb, Chlorthalonil or Fenamidon.
